Filter by:The general aim of the research is to provide scientific evidence that vibro-tactile stimulation (VTS) represents a non-invasive form of neuromodulation that can induce measurable improvements in the speech of people with spasmodic dysphonia (SD). This research addresses a clinical need to develop alternative or auxiliary treatments for a rare voice disorder with limited treatment options. A successful completion of the proposed work will be an important step in advancing laryngeal VTS as a therapeutic intervention for improving the voice symptoms in SD. Specifically, the scientific yield by achieving the specific aims is threefold: First, it will elucidate the unknown neurophysiological mechanism behind laryngeal VTS by documenting the neural changes associated with VTS. Second, it will establish that VTS can improve voice quality in SD. Third, by documenting that laryngeal VTS yields long-term benefits on voice quality in SD patients, it would provide a solid basis for a clinical trial that needs to address open questions on optimal dosage and duration of VTS-based voice therapy, the magnitude of the therapeutic effect across adductor and abductor SD and its long term efficacy.
The objectives for this research are to determine the mechanisms by which specific therapy tasks improve voice in age-related dysphonia, and the conditions that limit the extent of improvement. The central hypothesis is that targeted therapy tasks will improve voice, and that severity will determine the extent of improvement.
The purpose of this study is to pilot test a version of the intervention that has been tailored for participants with dysphonia. The study seeks to determine if the adapted intervention: a) increases perceived control over voice-related stressors and b) decreases stress and distress resulting from voice problems. The study will also explore the usability and acceptability of the program. The goal is to help people with voice problems achieve better voice and quality of life outcomes.
This study is a drug use investigation program of BOTOX. The objective of this investigation is to collect and assess information on the safety and efficacy of BOTOX injections in subjects with a diagnosis of spasmodic dysphonia in daily clinical practice. All subjects treated with BOTOX for spasmodic dysphonia after obtaining approval for the indication of BOTOX for spasmodic dysphonia will be included in this study. Approximately 400 subjects will be included in the study. The observation period per subject will be up to 12 months from the date of the first administration of BOTOX. The total study duration will be will be approximately 3 years from the date of approval for the indication of BOTOX for spasmodic dysphonia. BOTOX is a registered trademark of Allergan, Inc.
Investigators assess and compare postoperative sore throat and hoarseness in the group using the muscle relaxant and not using it during the operation.
Investigators assess and compare postoperative sore throat and hoarseness in the group maintaining moderate relaxation and deep relaxation during operation.
The purpose of this study is an evaluation of the effect of the reinforced endotracheal tube on post-operative hoarseness and sore throat undergoing thyroidectomy
Double lumen tube (DLT) needs to be intubated to isolate ventilations of left and right lungs for thoracic surgery. Post-operative sore throat and hoarseness are more frequent with DLT intubation than with single one. Which is may because DLT is relatively thicker, harder, sideway curved and therefore more likely to damage the vocal cord or trachea during intubation, and advanced deeper to the carina and main bronchus level. In the conventional method of intubation, DLT is rotated 90 degrees and advanced blindly to the main bronchus level after DLT is intubated through vocal cord using the direct laryngoscopy. After the blind advancement, the sufficient tube position needs to be gained and confirmed with the fiberoptic bronchoscope. In the bronchoscope guide method, after DLT is intubated through vocal cord using the direct laryngoscopy, the pathway into the targeted main bronchus is secured using the fiberoptic bronchoscope which is passed through a bronchial lumen of DLT. And then DLT can be advanced through the guide of the bronchoscope. In this study, we intend to compare post-operative sore throat, hoarseness and airway injury between the two methods. We hypothesize that the bronchoscope guide method can reduce the post-operative complications and airway injury because surrounding tissues of the airway can be less irritated by DLT intubation in the guide method than in a conventional. For a constant guide effect, we use fiberoptic bronchoscopes with same outer diameter (4.1 mm) which can pass through a bronchial lumen of 37 and 39 Fr Lt. DLT and cannot pass through 35 Fr or smaller Lt. DLTs. <Lt. DLT size selection> - male: ≥160 cm, 39 French; < 160 cm, 37 French - female: ≥160 cm, 37 French; < 160 cm, contraindication
The purpose of this study is to assess the effect of voice exercise and voice rest on subject's perception of vocal handicap and communicative participation following Botox injections for adductor spasmodic dysphonia.
Using a comprehensive approach of clinico-behavioral testing, neuroimaging and pharmacogenetics, the researchers will examine the clinical effects of sodium oxybate and the matched placebo on voice symptoms in spasmodic dysphonia and voice tremor.
